We have used Global Alarms for many years. The operators are quick to respond to alarms. The techs have always come out quickly to make any upgrades or repairs and are always courteous.

The folks at Global Alarm Systems are awesome and will treat you like family. When my office was burglarized on Christmas and again on New Year’s Day, these guys were there when I needed them most. They swiftly installed cameras, upgraded my security system, and caught the thief when he returned. Thank you Global!

“We switched to Globals wireless several yrs ago. It works great! Same great service. Thanks Global!”

In a world controlled by large corporations it is refreshing to work with a family owned business that provides that personal and customized approach in servicing their customers, but yet has the size and professionalism to handle customers with locations spread across multiple states. We have used Global Alarm not only for our primary business (commercial insurance agency), but also other business ventures, as well as my home, my parent’s home, and many of our employee’s homes. If you have ever tried to contact another service provider (gas, electric, cable…) and you get lost in a myriad of voice commands in their effort to keep you from talking to another human, then you know the value of a business such as Global Alarm where a representative answers the phone, truly listens, cares and will take care of your problem. I cannot provide a high enough recommendation for Global Alarm. We have had an outstanding experience with them for many years and look forward to working with them as we grow and expand in the future.

We have had Global Alarm in our home and business since late 1990. We have been very satisfied with the service and customer support. Great company! Awesome people!
